FASTENING FOR HARROW-TEETH.

SPECIFICATION forming part of Letters Patent No. 691,660, dated January'21, 1902).

Application led July 25, 1901.

Beit known that I, STALEY D. POOLE, a citizen of the United States,residing at Moline,

in the county of Rock Island and State of Illinois, have inventedcertain new and useful lImprovements in Fastenings for Harrow- Teeth;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. Y

This invention relates to means for fastening or securing barrow-teethin place upon the bars or supports therefor; and it consists,

substantially, in the improvements hereinafter more particularlydescribed, and pointed out in the claims.

The object of the present invention is to provide a clip or fasteningdevice of the character referred to which is simple in construetion andthoroughly effective in use and one also which is capable of beingquickly and readily applied without much labor and without special toolsfor the purpose.

A further object is to provide a clip or device of a constructionwhereby the fastening of the harrow-tooth is rendered as strong anddurable by the employment of ordinary castiron in the manufacturethereof as former constructions in which malleable iron is employed.

A still further object of the invention is to provide a clip orfastening device for the purpose named which is capable of being rapidlyproduced in unlimited1quantities with fewer defects than hitherto andalso with a much greater uniformity of the sizes thereof throughout.

tom .plan View. Fig. 6 is an end elevation looking toward the left. Fig.7 is a perspective view of the clip detached and taken from the innerface thereof.

Specific reference being had to the accompanying drawings, A representsa barrow-barv section constructed of metal and of substantiallysemitubular form, the longitudinal straight edges a a thereof being inthe same vertical plane, as shown. In the vertical or rounded side b ofsaid bar an opening c is formed for the passage of a pin or bolt d,which secures the clip or fastening device B to the bar, the said boltbeing provided with a nut e, which is screwed up tightly against thebar, as shown. My improved clip ktion to securethe barrow-tooth C inplace upon the said supporting-bar. At about the point of joinder orintersection of the hooked portion of the clip kwith the neck thereofthe said clip lor fastening device is formed with abolt hole or openingvl, corresponding with opening c in bar A, and the outer surface ofcessedatk, both to Vlessen the weight of the clip and to provide a datbearing for the head Z of the bolt, as well as a pocket or receptaclefor receiving such head lin a manner to protect and partially concealthe saine. The upper and lower webs or angesnn thus formed on the outersurface of the clip also serve as abutments for the said bolt-head, bywhich the bolt is prevented from turning, and thus is increased strengthalso impartedto the structure, besides bringing the several parts orelements of the clip or fastening device into snug andcompact'relationship. Thesaid Webs or anges n n are also strengthenersfor the clip or fastening device, as is obvious.

The neck portion of the clip or fastening der the said hooked portion ishollowed out or re- IOO vice is also formed on its upper and lowersurfaces with a longitudinal rib or flange o, which for the whole orpart of their length abut against the edges of adjacent portions of thelongitudinal straight edges of the supporting-bar A, and thus is myimproved clip or fastening device also prevented from turning inwardlyor axially in a horizontal plane with respect to the major axis of thebarrow-tooth. Said ribs or iianges also serve as an abutment orresistance in the tightening of the parts in place by means of the nuton the bolt. The said clip is also ribbed, as shown at p, for thepurpose of increasing the strength of the clip at points thereof subjectto the greatest amount of strain in use. On its inner or engaging facethe hooked portion of the clip or fastening device is formed with anotchor recess s, the sides of which intersect or join each other insubstantiallya single right angle, as shown, and said sides unite withadjacent portions of the straight edges a t of the supporting-bar informing an opening in which the tooth C fits, one corner or angle ofsaid tooth having a double bearing on said bar edges a ot, and two ofthe sides of the tooth being firmly clamped or embraced by the two sidesof said notch or recess. Of course with barrow-teeth of other shapes incross-section the form of the notch or recess in the clip will be madeto correspond therewith.

From the foregoing description and accompanying illustrations it will beseen that my improved clip or fastening device is very simple, as wellas secure and effective in use, and it will of course be understood thatI do not limit myself to the details of construction and arrangement ofparts employed herein in explanation of my invention.

By my construction I am enabled to employ ordinary cast-iron in themanufacture of the device and secure equally as good, if not better,results therefrom than are to be obtained from many former devices ofthe kind which must be made of malleable iron in order to render them atall desirable or effective.

My device is simple and easily molded, and large numbers of the partsthereof can be putin the sand one day and made ready to be delivered bythe next, and thus are large orders enabled to be filled promptlywithout incurring any loss to the factory, as in the instances abovementioned with regard to malleable-iron clips or fastenin gs. Moreover,the fastening-bolt employed by me is an ordinary machine-bolt includingno special features of construction, and thus the purchase of the boltsis not confined to parties having special facilities for making them,since said bolts are always carried in stock by almost all manufacturersand can be promptly furnished in any quantity on the placing of orderstherefor.

By the use of my improved clip or fastening device agreat advantage ishad in the fact that less labor is required in constructing or puttingup the harrow, there being no fitting of castings to be performed and noclipping or grinding of burs, the device being all ready for use as itcomes from the rattlingmill. The clamping capacity of myimproved clip isalso very great, and the device forms a fastening for the harrow-toothequally as secure as former malleable-iron fastenings for the samepurpose.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

l. In combination with a supporting-bar substantially U -shaped incross-section, a substantially hook-shaped clip having its shankconstructed to abut against and partially enter between the edges of thebarand its hook confining a tooth between the same and said edges, and afastening device located between the hook and shank for securing andholding the parts together.
